Project description:Physical activity improves overall health and counteracts metabolic pathologies. Adipose tissue and bone are important key targets of exercise; the prevalence of diseases associated with suboptimal physical activity levels has increased in recent times as a result of lifestyle changes. Mesenchymal stem cells (MSCs) differentiation in either osteogenic or adipogenic lineage is regulated by many factors. Particularly, the expression of master genes such as RUNX2 and PPARγ2 is essential for MSC commitment to osteogenic or adipogenic differentiation, respectively. Besides various positive effects on health, some authors have reported stressful outcomes as a consequence of endurance in physical activity. We looked for further clues about MSCs differentiation and serum proteins modulation studying the effects of half marathon in runners by means of gene expression analyses and a proteomic approach. Our results demonstrated an increase in osteogenic commitment and a reduction in adipogenic commitment of MSCs. In addition, for the first time we have analyzed the proteomic profile changes in runners after half-marathon activity in order to survey the related systemic adjustments. Interestingly, proteomic data showed the activation of both inflammatory response and detoxification process. Moreover, the involvement of pathways associated to immune response, lipid transport and coagulation, was elicited. Notably, positive and negative effects may be strictly linked.

Project description:While exercise effects on the immune system received increasing attention in recent years, it remains unclear to what extent gender and fluctuations in sex hormones during menstrual cycle influence immunological responses to exercise. Using a previously published microarray data set, we investigated mRNA changes induced through exhaustive exercise (half-marathon; pre-exercise and post-exercise [30 min, 3h, 24h], whole blood culture ± LPS (1h)) with a specific focus on sex differences (women in luteal phase vs men). Inflammation related pathways, TLRs, cytosolic DNA sensing and RIG-I like receptors were differentially activated between sexes in LPS-stimulated cultures. Genes differentially regulated between sexes included TNIP-1, TNIP-3, IL-6, HIVEP1, CXCL3, CCR3, IL-8 and CD69, revealing a bias towards less anti-inflammatory gene regulation in women compared to men. In addition, several genes relevant to brain function (OLIG2, TMEM106B, DDIT4, and KMO) showed differential activation between sexes. Some of these genes (e.g., KMO in women, DDIT4 in both sexes) potentially constitute neuroprotective mechanisms. These data reveal that the exercise-induced change in gene expression might be gender and menstrual cycle phase dependent.

Project description:Few data are available that describe how probiotics influence systemic metabolism during endurance exercise. Metabolomic profiling of endurance athletes will elucidate mechanisms by which probiotics may confer benefits to the athlete. In this study, twenty-four runners (20 male, 4 female) were block randomised into two groups using a double-blind matched-pairs design according to their most recent Marathon performance. Runners were assigned to 28-days of supplementation with a multi-strain probiotic (PRO) or a placebo (PLB). Following 28-days of supplementation, runners performed a competitive track Marathon race. Venous blood samples and muscle biopsies (vastus lateralis) were collected on the morning of the race and immediately post-race. Samples were subsequently analysed by untargeted <sup>1</sup>H-NMR metabolomics. Principal component analysis (PCA) identified a greater difference in the post-Marathon serum metabolome in the PLB group vs. PRO. Univariate tests identified 17 non-overlapped metabolites in PLB, whereas only seven were identified in PRO. By building a PLS-DA model of two components, we revealed combinations of metabolites able to discriminate between PLB and PRO post-Marathon. PCA of muscle biopsies demonstrated no discernible difference post-Marathon between treatment groups. In conclusion, 28-days of probiotic supplementation alters the metabolic perturbations induced by a Marathon. Such findings may be related to maintaining the integrity of the gut during endurance exercise.

Project description:Studying microRNAs in the immune cells of athletes offers a novel perspective on the molecular regulation of immune function and recovery, potentially uncovering strategies to enhance performance and resilience to physical stress. However, PBMC microRNA expression in endurance athletes, such as runners and cyclists, remains underexplored, especially with regard to sex differences. This study aimed to (i) assess sport- and sex-specific differences in PBMC microRNA expression induced by acute aerobic exercise in runners and cyclists, (ii) evaluate the impact of maximal (trial A) and sub-maximal (trial B) exercises, and (iii) examine correlations between PBMC microRNAs and exercise performance. Methods: A total of 58 participants were included: 22 runners (9 females), 18 cyclists (9 females), and 18 active controls (9 females). Participants underwent VO2max and time-to-exhaustion tests, with blood samples collected pre- and post-exercise to analyze PBMC microRNA levels. Results: Runners exhibited a stronger microRNA response than cyclists or controls, with significant sex-based differences. After maximal intensity exercise, 279 microRNAs (255 upregulated) were altered in runners, compared to only 7 microRNAs (none upregulated) in cyclists. Exercise intensity and duration had sport-specific effects on microRNA expression. Time-to-exhaustion in runners and weekly training volume in both groups were significantly associated with changes in PBMC microRNA profiles. Conclusion: This study reveals that PBMC microRNA expression in response to acute aerobic exercise is sport- and sex-specific, providing new insights into the molecular adaptations of endurance athletes and their relationship to athletic performance.

Project description:This experiment was designed to identify changes in gene expression in the brain (specifically the hipocampus) in relation to variable levels of voluntary exercise. Male C57Bl/6J mice were weaned onto a low fat diet (LF; Research Diets D12329, 11% kcal fat) and given continuous access to exercise wheels (30.3 x 20.6 x 26 cm; Mini Mitter®, Nalgene® Activity Wheel for Rodents) at ten weeks of age, for three days (n=96). Six mice had their wheels locked to act as sedentary controls (sed). Animals were considered to be high runners (HR) if they ran >= 5 km/night and low runners (LR) if they ran <= 2 km/night. Middle runners (MR) were chosen randomly from the population of animals falling between the high and low groups. This series is comprised of array results from three parallel experiments comparing HR versus sed, MR versus sed, and HR versus LR. Six hybridizations were performed for each of the three comparisons (3 forward-labeled, 3-reverse labeled) to account for dye-incorporation differences. One slide from the HR vs LR experiment was broken during processing, so only five are included from that group.
